Product Details

SODIUM METATUNGSTATE CAS#12141-67-2

Sodium metatungstate is an important tungstate salt with good stability. In aqueous solution, metatungstate ions can react with a variety of metal ions to produce different tungsten compound precipitates. It can also participate in some REDOX reactions, under certain conditions, the valence of tungsten can change.
